dTPS accell enriches fuel based on throttle movement and dMAP accell enriches fuel based on manifold pressure change. You can use both or either when running speed-density.
IAT density correction provides a means to apply a portion of ECT to the IAT measurement to more precisely calculate the actual temperature of the air entering the combustion chamber.

Have you tried disconnecting your PSP switch to see what happens?
I've been driving my S13 with PSP disconnected (swap harness won't reach) for years with no issues.
Unplug and replug all of the connectors around the coil. You can get the no ignition signal DTC with no other symptoms/issues if the connection from the coil and power transistor to the resistor, o...
As a test, you can remove the calum board and [url= URL=http://www.nismotronic.com/Help/Install.html]relocate CJ2 back to CJ1[/url] which will return the ECU back to stock operation.
The issue I saw in your log was with the MAF voltage, which has nothing to do with the fuel map, but if the problem is solved, maybe it was some intermittent problem with the MAF.
Anytime anyone needs help diagnosing something, please email an unfiltered log (TCL) and TCD to John and myself. To capture an unfiltered log, make sure all Recording Triggers on the Logging Settin...
Here are some scatter plots of MAP vs. TP and MAP vs. MAF Q. These were made using over 15000 data points collected over a 30 minute drive with varying load, rpm, throttle and speed conditions.
